Question 9
How many breaths in one minute?
Predict how many breaths you will take in one minute. Predict the number at rest and then predict the number after exercise.
While you sit at rest, count the times you breathe in during one minute. This is your breathing rate, at rest.
Then after one minute of gentle exercise, count your breaths again for one minute. This is your breathing rate after exercise.
Make a table from your results. Use these column headings:
| My prediction of breaths in one minute at rest | My prediction of breaths in one minute after exercise | Number of breaths in one minute at rest | Number of breaths in one minute after exercise |
|:-:|:-:|:-:|:-:|
